Frame.

The present invention embodies a conven- 1n the present in- V and 5, which are connected and reinforced by the longitudinally extending vpieces 6. The section 3 has a superimposed part 7 for the support of the wires 8, from which the reinforcements and fastenings are y formed or constructed. This superimposed portion of the section 3 has upright parts 9 connected at their upper ends by a longitudinal piece 10. The 'uprights 9 are provided with supporting hangers'or nails l1 for the support of several groups of wires 8.

A portion of the superimposed part of the section 3 of the frame supports the cornpacting mechanism for the bundle of ,rein-` forcements, said mechanism to be described later. Thesection 2 of the frame has asuperimposed portion 12, between which and the top ofthe lower portion'of the section 2, several compartments 13 are formed, for the reception of drawers 14, which may contain various 'tools and additional parts, whereby the reinforcement 'forming mechanism may be repaired. `One of the compartments 13 has a suitableelectric motor 1'5 mounted therein, for furnishing power to the reinforcement construction mechanism. Y

Reinforcing 'constructing mechanism frame.

vMounted upon the section' 2 of the frame 1 and superimposed in spaced relation by meansjof the end pieces '16 and 17 isv a'bed 18, which may be solid or open or skeleton" in construction. By spacing theI bed 18, a suitable elongated compartment 19 is provided for the reception of parts of said mechanism. One end of the bed has a rectangular flange 20, thereby providing a partitioned-off space which may Acontain small tools or waste andan oil-can or the like, for use in connection with the machine.

Also mounted upon the bed isv'aplate 21,V

which is substantially U-shaped, `as showin in top plan view in Fig. 3. Rising upwardly 'fromithearms'22 of the plate`21 and crossconnecting thearins is an arched bracket 23. Also rising upwardly from theplate 21 on the end thereof opposite the bracket 23 and secured ythereto isa second bracket 24. vRis- Mounted in the bearings ofthe brackets whereby power lmaybe transmitted to theV These guide rods 26 and shaft.l 29 and its mandrelrend. "One end of the shaft 29 is provided with a socket 33 for the recep'tion'of 'the smallest type of needle 34, on which the smallestsize of spi-ral rein# forcement is constructedV Aor coiled. Thisr socket 33 is counterbored to provide-thebore 35 for the receptionof a bushing 36. This Vbushing y36is utilized, as shown in VFig.2'4, -when' employing the smallest needle; 34.

needle, thereby holding the bushing 'and the.

needle securely in the bore 35; The exterior ofthe mandrel end of the shaft 29 is threaded, as shown4 at-38, to be engaged by the threads 39 of the largest tubular needle 40.

'This needle may be either tapered or cylindrical and is tubular and may be ofk any suitable diameter. One end of the' tubular needle 40 has an annular flange 41, between which and the bracket'23 suitable ball bearings42 are interposed. These ball bearings may 'be of any" suitable construction, and

maybe retained in place'by any conven-l' tionalv form of retaining plate'or'means 43. Obviously, the threads 33 and' 39 vare de signed Vto be of such pitch and so formed that while the mandrel lor shaft 29 lis rotat-V ing in one direction,the threads will remain in constant engagement, lin such wise as to prevent the needle 40 from unscrewing, the

ball bearings actingl to reduce the friction tok a minimum; However, 4when using the larger needle 40, the bushing 36 vis removed, and an intermediate tubular needle v44 is inserted in the bore 35, there being a counter-v sunk set-screw 45 threaded through the wall of the mandrel and in contact with-'the needle 44.v The smallest-needle 34V is likewise tubulan These needles 34, 40 'and 44,"at

Vtheir lfree ends,'are provided with diametrically oppositely disposed slots 46. Then forming a spiral reinforcement, for fastenroo ing orspiral stay,` whether conicaly or tapered or the convolutions of uniformdiameter, al wireV of requisite length is inserted telescopically into the needle', until the inserted end contacts with the'end of thesoc'ket 33 of the mandrel. The' wire Sis then bent, so as to engage either one ofthe slots 46, to

Vprevent the wire from rotatingin the needle.

The wire is bent in lthe manner shown in Fig. 7, or Fig. 8. It is apparent'that the various needles 34, 40 and 44 will form" reinforcements or-stays of different 'diameters Further, additional needles of larger diameters-may be employed, and, if so desired, the vneedle 40 may be vused singly, that is without the intermediate needle44. When using the intermediate needle singly, a rein-V forcement is constructed, the diameters of the convolutions of which are intermediate rre iso

spiral helix will be formed or constructed,

and will be automatically discharged on the return ofk the carriage to its initial position. Rising upwardly from one of the armsof the plate 21 yis a bearing bracket 47. An opposed bearing bracket 48 is bolted or otherwise secured at 49 to the other arm 22 of the plate 21. MountedV inthe bearing brackets 47 and 48 is a shaft 50 to be driven.

Fast upon the shaft 50 by means of the set screw 51 is a spur gear 52, ythe hub 53 of which may be ofvany suitable construction, preferably partially hollow, as indicated at 54. The marginal flange of the hollow 54 is formed with clutch teeth 55. The spur gear may be otherwise fastened or keyed to the shaft 50. Loose upon the shaft is a sprocket 57, one face of which is provided with a clutch hub 5.8,' having clutch teeth 59, adapted to coperate with the clutch teeth ofthe hub of the spur gear 52. Arranged in a hollow of the clutchhub 58 are antifrictional ball bearings 61 and anti-frictional circular plates 62 and 63, the :ball bearings being intermediate the two plates. Suitable retaining rings 64 provided, for'retaining the balls in their proper positions. Interposed between the plate 62 and the hollow of the hub 53 of the spur gear is a coiled spring 65, which holds 'the two clutch members normally separable. Since the shaft 50 is a driven shaft and the spur gear 52'is fast thereon, the sprocket 57, throughthe medium of the sprocket chain 66, will impart longitudinalmovement to the carriage on its Yguide rods, aswill hereinafter be set forth, when the clutch members are interengaged.V The bearing bracket 47 also has mounted, therein a stub shaft67. This stub shaft has a reduced portion 68, 55 which passes through the bearingsin the bracket 47, and, by tightening upon the nut 69, the shoulder of the stub shaft willbe drawn tight against one face of the bracket 47, thereby holding the stub-shaft firm. In

160 order to provide a firm bearing for the reducedj end of the stub'shaft and to insure `the rigidity thereof, that portion of the bracket through which the stub extends is enlarged, as shown 'at 71. However, this ary65 rangement yor construction maybe varied as desired, in orderto suit other conditions.` The stub shaft 67 has a headr72, between which and one face of the bracket 47, spur and bevel gears 73 and 74 are loosely mounted. These gears are designed to rotate together and may be made, if Vso desired, in one piece, or separable and secured together by suitable screws 75, preferably the latter.VV Fast upon the shaft 29, by means of a set screw 76, isa bevel pinion 7 7 which meshes with the bevel gear 74. .Obviously, when power is transmitted byV the beltV 31, the shaft 29 is rotated, imparting movement to the needle, and through the'medium ofthe gears 52 andf 3 (which intermesh) and the bevel gear 74 and pinion 77, power is transmitted to theshaft 50, and when the clutch connections of the gear 50 and the sprocket 47 are interengaged motion is imparted to the carriage. This motion is impartedfinstantlywhen the carriage starts its. operating stroke. It might be said that when the smallest needle is dispensedV with, whereby. either one orboth of theintermediate and larger needles may be used, the set-screw 37 is detached and threaded into the radial bore 78 of the mandrel end of the shaft 29. V i

Guide cmd feed caw'z'age for thaw/ire.

Mounted upon the guide rods 26 and 27 is a guide and feed wire for the reinforcement forming needle. This carriage 79 comprises the opposed plates 80 and 8l, and

may be of anyV suitable construction,'prefer ably as shown. These plates, at their upper portions, are provided with laterally curved arms 82, in bearings of which suitable,V pins 83 are mounted. Y Journaled on the pinsare grooved rollers or pulleys 84 which ride the upper guide rod 26. The grooves of these pulleys or rollers 84 are deep enough so that the flanges of .the pulleys will engage considerably on either side of the guide rod, preferably almost one-half thereof, thereby insuring guiding of the carriage and preventing any lateral displacement or uncer-v tainty of the proper position of the carriage. y Also journaled in'bearings of the plates 80 and l81 are the pins 85 and 86. Journaled .upon the pin85 is agrooved roller or pulley 87 identical in construction with the pulleys orV rollers 84. This roller or4 pulley 87 en ages the under surface of the guide rod 26, coperating with the pulleys 84, so as to hold the carriage in position and" to prevent vertical displacement. A pulley or roller 88 is journaled uponv the pin 86'and is also similar to the pulleys 84 and` 87, and engages the under surface of theguide rod 27'. This pulley or roller 88,'in addition to also preventing vertical movement of the carriage, preventslateral movement of the carriage, and holds the carriage in perpendicular position with relationto the guide rods 26 and 27. It is obvious that when the larger needle 40is employed, the opposing plates 80 and 81 may be further separated than at present illustrated, and in such an instance the rollers or pulleys .81, 87 and 88 may be dispensed with, and longer pulleys substituted. In other words, pulleys iden# tical with those illustrated, but supplied with end bosses, such as shown at 89 in Fig. 27, maybe provided for holding the plates 80 and 81 furtherspaced. A. bumper block 90 is provided and it has'a reduced portion 91 which is disposedV betweenthe two plates 80 and 81, there being a transverse bolt 92 extending through the plate and the `block for securing the same securely in place, as well as hold-ing the platesin their spaced relation. Secured to the plate 81 isa bracket 93. Mounted upon a stub screw or the like 91 (which is threaded into the bumper block 90) is a guide roller or pulley 95 provided with a beveled flange 96 on oneend, preferably its upper end. Mounted in the Vbracket 93 is a -stub bolt 97, on which a roller or pulley 98 is journaled.l This pulley or roller 98 also has a beveled flangeI 99. The pulleys or rollers 95 and 98 are arranged at right angles to each other, the beveled flanges 96 and 99 overlapping the cylindrical portions of the rollers or pulleys respectively. It is clear that the pulleys or rollers 95 and 98 are disposed a little below and offsetzlaterally from the needle, and after the wire 8 is inserted into the needle and bent, the exposed portion of the wire is inserted between the two rollers or pul-v leys 95 and 98, the overlapping flanges acting to hold thewire in the manner shown in Figs. 2, 3 and 9vclearly. .The rollers or pulleys 95 and 98 act as a wire retainer or feed or guide, and further act as a letfout means for the wire as it is being fed and, as the needle rotates. in the direction of the arrow az" in Fig. 9,.the wire is coiled upon the exterior of the needle in a spiral helix, either with the convolutions of uniform die, ameters vor in graduallyvincreasing diam-- eters, ,depending upon the type of needle used.: Arrangedv between the plates 80 and 81 is a needle guide 100, whichV may be of any suitable construction,preferably as illustrated, and through the bore 101 of which the needle telescopically extends. This guide, on one face thereof, has `aslight depression 102, to be engaged bythe end of the shank of a set-screw 103 threaded through' the plate 81. When employing the larger needle, the guide 100 may be removed, and in this case the needle passes between the two plates 80 and 81, and since the larger needleis reinforcedby the intermediate nee-,1

dle, vibrations of the needles are prevented; Projecting laterally from the plate 80 is a projection 1011, the purpose of which will appear in connection with the needle end retaining device' The lower endS 0f. thepletes.

25. It is obvious that on the return strokeof the carriage `the bumper block contacts with the buffer plate, thereby absorbing the shock. 'The buffer plate 113 is angular in cross section. and its flange-117 acts' asi il. guard to prevent thewire from engagement between the buffer plate and the bracket 25.

Oawa'af/.e reime/a mechanism. After the carriagehas made its forward movement it has been found desirable' in the present instance to provide a positiveireturn mechanism forl theI carriage. Thls mecha-` nism comprises a conventional formfofcham 126, one end of which is connectedto'an l eye. 127 of the dog 107 ,and its other end connected at 128 to the vtensioned coiled spring 1294 The Spring 129eintu1'11JeeI1:

nectd at's1'30 rto the end: piece 17,' which fsupports the bed. This chain 126 also passes over the pulley 112, and over an additional pulley 131 AWhich is carried bythe under surface of the bed-k near the end piece 17. It is apparent that the chain 126 is arranged in 'apairfof loops, one of Which engages said pulleys ',112 and 131, the other engaging a pulley 132 which isconnected to a second tensionedcoiled spring 133. One end of the spring133 is' connected toa hook 134 which is carried bythe endpiece 16. When the carriage" is making its reinforcement forming stroke, a pulling action is imparted on the chain 126, thereby tensioning both springs 129 and 133 simultaneously, and the actionsof these springs are of such character,'one equalzingv the other, in order to relieve the excessive strain on the chain 66 and Yits-f'coperating parts'. As soon as the carriage reachesY the end of its reinforcement forming stroke, the clutch mechanism ofthe shaft 50 -is openedautoinatically, and, through the'tensioningaction of the springs 1-29jand 133, the carriage 'is'returned to its initial position.

Clutch releasing mechanism.

AThe hub:k 58 of the sprocket 57 has an annular groove '135, to be engaged bythe forks v136of the lever 137. An'arched plate 138 is bolted or otherwise secured to the arms 22 of the plate 21, and this plate 138 has a reduced portion 139, engaging between the legs4 of the 4arched bracket 23. f Mounted upon the reduced portion 139 is 'an overhanging arm or member 140,7between the overhanging part .of which and the reduced ,port-ion the lever'137 is pivoted at 141. One en d of the lever is provided with an upsi'tanding pin 1425 Pivoted on'one endof the plate 138, bythe screw stud 143, is a detent 144 provided with a notch 145,V to be engaged bythe upstanding pin 142, when the lever 1,37'is m'ovedpiyotally.' By means of a'leafv spring 146, secured i-nany suitable manner to one leg of thearched bracket 23, for instance, as shown at-147, and which engagesthe detent 144,* said detent isheld in Contact with' the upstanding pin 142. A rocking pin 148 is mounted in a bearing ot the plate 138, and on its upper end acam arm-'149 is fixedand on its lowern end a curved arm V150 is Vsecured by means of the set scre\v,150a. The forks of a4 connector or couplerv 151 are pivotally connected, as at 152, to the end of the curved arm 150. The arm'1149engages one end of the lever 137, and vvhenV a pulling action imparted upon the" connector 151, thereby rocking the pin 148, thearm 149 Will oscillate the' lever 137 and throw the two clutch members-of the shaft 50 into,` coperation. Instantly revoluble movement isUimpa-'rted tothe sprocket 57 and', in turn, the chain 66 is actuated, the

carriage'k then being started on itsreinforcement formingstroke. When the ycarriage reaches the end of such stroke, the head ot the pinf109 will contact with one edge'of the detent 144, actuate the same against the Vaction of the spring 146, in which case the pin 142 Will disengag'e from the notch 145', and, through the action of the spring between the two" clutch members, vvvthe clutch 4members are separated, the' sprocket 57 then remaining idle. The carriage is then free to returnv to lits initial position through the mediumot the carriage return mechanism previously',described. f l

V'Uorrz'age detenty mechanism. Mounted uponr the bed 18 adjacent the bracket 25 is :a bracket plate r154, preferably or' thel design or construction shown in Fig. This Vbracket plate has a vertical bore 155 for the reception of the pin 156, there being a 'collar 157 secured upon the pin. 2A. coiled spring V158 surrounds the pin 156 and isin# Yterposed'between theccllar 157 andthe collar 159 which rests on the bed, the Aopening' v160 through the bed and throughl which the pin 156 extends being smaller than the bore 155. Therefore, the collar159 will be rsupported in position. The lower: end of the pin 156 hasany eye 1,61. The yupper endl of the bracket plate 154 has a laterally extending bifurcation 162, in which a detent 163 is pivotally mounted upon lthe pin 164. vThe under `facevof the detent has a depression 165, to be vengaged by the upperend oi' the pin'156, to hold the detent normally in p'osi-` tion',shoWn in'Figs. 5 and'6. One endedge of thedetent 163-'isV provided with a semibers are connected or thrown Vin clutch. I

Thisvenables the carriage to befree'to start on its reinforcement lformingstrokefat the requisite time when poweris imparted te the'chain 66 formpvingthe carriage. In orderto accomplish the simultaneous actuation of the pin 156 and the pin 148, a cable 168 is Iconnected tothe eye 161, and a rod 169 is attached to the connector 151. A cable 170 is connected tothevrod -169and passes over the pulley171.- The ,two cables 168 and' 170 are connected tol the eye bolts172, which are adjustably connected to lthe crosshead *..plate KY173 by the nuts 174.I Theeye bolts maybe easily adjusted by re-arranging the-nuts, and depending from the crosshead plate is a hook 175, to which a cable 176 is connected, This cable 1-76`is`,-in turn,

lthe bracket is substantially U-shaped.

connected to the hook 177 o f the foot lever 178, which is pivoted at 179 between the joist of the iiooring, shown clearly in Figs. 1 and 4. 'lhisfoot lever is provided with a foot-engaging knob 180, which, when he levei` 178, the detent 163 is released simultaneously with the closing of the clutch members, allowing the carriage tol proceed on its reinforcement forming stroke, owing to the power being imparted to the chain 66 at the same time. y

Needle-end retaining nwchanz'sm;

When using the needles 34 and 44, it has been found imperative to provide means for retaining the end of the needle concentrically with the mandrel, and to prevent vibration, since the needle rotates at a rapid speed. T his means comprises a bracket 184, which consists of a plate 185 provided with a threaded extension 186 penetrating the stud rod 120, there being a nut 187 on the extension to holdV the plate securely connected to the rod. This plate 185 is arched, as shown, so as to remain rigid with relationto the stud rod. To complete the bracket, forks 188 project from the plate 185, and are spaced, as. shown; consequentl needle-end retaining plate Y or element 189 is provided, and extending laterally from the upper and lower edges'thereofare pins 190 engagingbearings in the,` forks 188; This needle-'end retaining element has -a circular opening 191, through which the end of the needle (that is', either the needle 84 or 44) partially extends', that is, after the needle has been threaded with a wire 8,-to be formed,V into a coil or spiral. This retaining element has a crotch 192v provided with an eye193, and also projecting fro'm one endl of the` plate 189 is a curved arm 194,whicli, whenY theV retaining element is positioned, 4as shown in Figs. 8 and 7, with the needle end protruding through the opening 191, contacts with the stud rod 120, so as to hold the'retaining .element in position, and wherebyV the needle end may revolve freel'yin the opening'191. A collar 195 is slidably mounted upon the stud rod 120 and is designed tobe secured in. adjusted positions by the set screw 196. rlhe collarcar ries an eye 197, to which one end of a spring 198 is connected. The other end of the spring is connected to the eye 198, thereby holding the arm 194 in contact with the studrod 120. By.V adjusting the collar 195, the tension of this spring may beincreased or decreased, as Ymay be found necessary .with relation to the pivot190, that wheny the ing the same suiliciently to disengage the opening 191 fromrthe needle-end. It is to be noted that the crotch 192'is so constructed 7 5 retaining element is moved or oscillated sufiiciently, thespring 198 will contract on the other side ofthe pivot 190, so as to oscillate the retaining element entirely clear of the needle,.as shown in dotted lines inF ig. `3. Owing tothe constructionof the crotch and; l the connections orarrangement of thespring 198, the spring will retainthe retaining v plate, either in engagement with the needle'- end orv out of engagement. -VVhen the retainingv plate is moved entirely free of `the needle and the carriage has reached the end of'its movement toward its initial position, the curved extremity 199 of the arm 194 will engage the projection or4 plate 104 of 99 the carriage, assisting in'retaining the carriage in its initial position, even though the springs 129v and 133 are still under tension, and the dog 107'is inengagement with the detent-168. rloweverfwhen the carriage starts on its reinforcement forming stroke, the projection 104 will coperate with the extremity 199 of thearm 198, in` such wise as to oscillate the retaining element 189 to its initial yposition Ywith the opening 191 1,00 receiving the end of thefneedle, thereby f preventing excessive vibration of theneedle, whichv would other-wise be dueto the rapid revolution thereof. l 1

Bundling or' binding mecham'sm'for 4the rez'n- 105 foreen/tente.l Mounted upon the longitudinally extending piecesl6' (which brace the uprights 55 of the auxiliary sectioni)` isi-a reinforcementl kbinding mechanism, i lwhich comprises a pluralityo-f guide members 200 having channel guides 201.1 Mounted in the channel guides are rack frames 202, arranged 'in pairs in eachvof the .channel guides. 115

Each rack frame is elongated-and-rectangular, as illustrated, andlhas an elongated opening 203. T he lower wall of the opening'of one rack frame of each pair is provided with rack teeth '204'and the upper 1,20A

wall of the opening of the other rack frame of each pair is also provided with'rack teeth 204g. Mounted ina bearing 206 of thesection 2gof the frame of the machineand in bearings 207 of the walls of the guides 200 is a driven shaft 208, which is provided with a plurality of pinions209, so engaging the teeth of the' rack frames that when the shaft 208 is rotated in one.A direction, therack frames are moved slidably in their ,channel 13,0

I base jaw.

guides in planes toward each other. When the shaft 208 is rotated in vthe opposite direction, the rack frames are moved in planes inthe opposite direction. Secured to and mounted upon the upper edges of the rack frames by means of screws 210 are com-y plemental reinforcement binding jaws, which are arranged in `opposing series. Each series consists of nests of jaws, one nest carried by each rack frame and comprising a base jaw 211 and two additional jaws 212 and 213. Thebase jaw is curved, asvshown, and the jaws 212 and 213 are correspondingly constructed, so that one will fit within theother and the two will fit the These bindingV jaws are disposed beneath the conventional form of hopper 214,through which the reinforcements or helices 'as theyare discharged from the needle pass, and, subsequently, deposited between the jaws, k as will be obviousjfrom an examination of Fig. 1 together with Fig. 21. The reinforcements or helices as they are` discharged and, subsequently, passing through the hopper, contact with the abut'- ment 215, which is supported on the pieces 6 by the hooks216. Theends ofthe reinforcements or helices contact with this abutment, so thatthe ends ofthe helices or reinforcements are even or flush, when formed into bundles by the jaws. After sufiicient reinforcements are deposited between the jaws, the shaft'208 is rotated in the direction of the arrow c, moving the rack frames in planesv toward each other, likewise moving the jaws, which will compact the reinforcements into small and tight bundles. The additional jaws 212 and 213 are secured by theV screws 217 to the jaws 211. These screwsalso penetratethe'upper parts of the rack frames- Large bundles of re inforcements may be compacted by the base jaws211, and'byv using both of the addi-v tional jaws 212 and 213,Y as shown in Figi 20, small bundles of reinforcementsmay be compacted. `Intermediate bundles( may be formed, by removing Vthe jawsV 213. Larger base jaws maybe employed, if so desired, in which case additional complemental jaws may also be used, whereby the bundles may' be varied in size. The base jaws 211 are provided with extensions 218, which act to guide the reinforcements to and between the aws.

J The driving shaft 219 of the motor 15 is provided with a pair of fast pulleys 220 and 221, the latter being grooved, as shown at 222.V Mounted upon the driven shaft 208 are loose pulleys 223 and 224,`the latter`-hav ing a groove 225. Collars 224iL and 223a are secured on the shaft 208 by means of the set pins or screws 224". These collars are located on the shaft 208 in positions in con tact with the pulleys 223 and 225, in order to act as abutments to prevent movement of the pulleys 223 and 225. The pulley 224 is immediately under the pulley 221, the two being engaged by a round belt 226 which is twisted or crossed, as shown at 227. Engaging the pulleys 220 and 223 is a fiat belt 228. The loose pulleys 223 and 224 have clutch hubs 229 and 230, and keyed upon the driven shaft 208 is a double clutch mem ber 231, the clutch teeth 232 and 233 of which are designed to cooperate with the clutch teeth of the clutch members 229 and 230, as will be hereinafter obvious. r1`he clutch member 231 has a groove 234 engaged by the forks 235 of the lever 236 which isv pivoted at 237 to the longitudinally extending piece 6 of the main section 2 of the frame. An operating rodv 238 having a handle 239 isL mounted in a guide 240 and has its end pivoted at 241 to the lever 236. The handle 239 of the operating rod is ar' ranged in close position to the bundling mechanism so that an operator when handtying the bundles of reinforcements, may operate the rod and shift the clutch member 231. Interposed between the clutch members 229, 230 and 231, as shown clearly Ain Fig. 23, are coiled springs `242, which surround the driven shaft 208. By means of these 'springsthe 'clutch member 231 is heldin a neutralposition, as shown in Fig- 23. It is obvious that when the clutch member 231 is moved toward the'pulley 223 to engage the clutch member' 229, the shaft 208will be driven in the direction of the arrow c, moving the jaws in planes toward each other, thereby compacting the reinforcements. Mounted `upon Vand rotatable with the driven shaft 208is a ratchet 243, which is engaged by the pawl 244, so as to hold the Acompacting aws in their positions moved toward each other, to hold the bundle compact while the same is tied. However, after tying the bundle by hand, the pawl may be disengaged from the ratchet byapplying hand pressure on its handle 245, in whichcase the driven shaft 208 is free to rotate in the opposite direction. This opposite rotation-'of the shaft 208 maybe accomplished by moving theoperating rod 238, whereby the clutch member 231 may be shifted toward the pulley 224 in order to engage the clutch member 230. Since the belt 227 is -crossed Vor twisted, the driven shaft 208 will operate Yin' the direction of the arrow c, which will' separate the jaws,then the bundle is free to be removed by swinging the-abutment v215 to one side. j

Operation.

To form the reinforcements or helices, a piece of wire of the proper gage is inserted into the hollow needle, the needle-end retaining device having been swung to one Y gagesthe butt end of the socket inthe inandrel. The wire is then bent so asl toengage thel diametrically-oppcositely disposed- Y slots/46 of the end of the needle.

The bent portion of the wire is then disposed in` engagement with-the guard-121, as shown in- Figs. 1, 2 and 3. Power is then furnished,

atethe clutch lever 137, so that its pin 142 will be engaged by the notch 145 of the de.`

tentf144. The clutch members and 59 will 'then engage, and, through the medium.`

Since the needle is rotating at a speed consistent with the movement of the carriage, the wire 8is coiledupon the outer circumference of the needle, in the c manner shown in Figs. 1, 2 and 3. When the carriage reaches the end of its stroke,
